Small-Business Month-End Recordkeeping Checklist for Canada
Use this practical monthly routine to organize receipts, expenses, income, mileage, invoices, and unresolved records before they pile up.
A useful small-business month-end checklist answers one question: can you explain each business transaction and find its supporting record? A short, repeatable review helps you catch missing receipts, unpaid invoices, incomplete mileage entries, and personal payments before they become year-end problems.
Recordkeeping note: This article provides general organizational information, not accounting, tax, or legal advice. Your obligations and the treatment of a transaction depend on your business structure and circumstances. Confirm uncertain items with a qualified professional.
1. Confirm the reporting period
Choose the calendar month you are closing. Keep the review bounded to that period so totals and missing items are easier to explain. If you operate more than one business, review each business separately. The Canada Revenue Agency (CRA) says records should allow income and expenses to be determined and recommends separate records for each business.
2. Gather source documents
Collect receipts and supplier invoices, sales invoices and income records, relevant bank and card statements, mileage logs, contractor bills, payment evidence, and notes explaining unusual transactions. A bank or card line alone may not contain enough information to explain what was purchased.
3. Review income and invoices
Compare recorded income with issued invoices and other sales records. Mark invoices as paid only when payment is supported. Keep a list of unpaid invoices and the next follow-up date. Do not silently treat expected money as received money.
4. Review expenses and evidence
For every expense, check the date, amount, supplier, category, business purpose, payment method, and receipt status. Separate personal and business portions where necessary. Flag uncertain classifications for review instead of guessing.
5. Record owner-paid items clearly
If an owner paid a business expense personally, keep the receipt and record who paid. Do not create a duplicate expense when the business later repays the owner. The accounting treatment can differ for a sole proprietorship and a corporation, so preserve the facts and confirm the treatment with your accountant.
6. Complete mileage records
For business driving, record each trip’s date, destination or generic business location, purpose, and kilometres. Keep beginning and ending odometer readings and records for each vehicle.
7. Reconcile and investigate differences
Compare your records with the relevant statements. Look for duplicate entries, missing transactions, unexplained amounts, and payments recorded against the wrong invoice. A difference should become a named follow-up item, not an invisible adjustment.
8. Finish with an exceptions list
Create a short list of what remains unresolved: missing receipt, category to confirm, invoice to follow up, mileage detail to complete, or owner repayment to review. Assign a responsible person and target date.
9. Preserve readable records
Keep records in a readable format and protect electronic files from loss. The CRA generally requires business records and supporting documents to be kept for six years from the end of the last tax year to which they relate, although exceptions can apply.
Frequently asked questions
What should a monthly business review include?
At minimum: income, invoices, expenses, receipts, owner-paid items, mileage, statement differences, and unresolved questions.
Is a bank statement enough proof of an expense?
Not always. It may show that money moved but not the supplier, item purchased, or business purpose. Keep the underlying receipt or invoice when available.
Should every uncertainty be fixed immediately?
Do not guess. Record what is known, flag what is uncertain, and obtain professional guidance where needed.
